Pros: Seferian-Jenkins is the prototypical "basketball tight end" in this draft, and he literally fits that bill, as he played hoops for Washington as a freshman before quitting to focus solely on football. At 6'6" with a thick build, ASJ possesses an ideal frame for a top NFL tight end.
He's a good pass-catcher and can make the difficult grabs as well as the easy ones. There's a natural fluidity and athleticism to his game, which is promising to see from such a big guy, and he's the kind of mismatch nightmare that will make NFL offensive coordinators salivate.
Cons: ASJ is not an overly polished product, and for someone with such rare natural ability he does not always dominate like he should. He caught only 36 passes for 450 yards in 2013, which are very underwhelming totals. The fact that he only averaged 1.69 yards after contact (h/t Rotoworld), over a full yard less than every other tight end on this list, raises concern as well.
He isn't a great route-runner at this stage, and he needs to be crisper and more purposeful with his movements. The same goes for blocking, as he is only an average blocker despite having the physical traits to be an outstanding one. These issues need to be corrected immediately for him to be successful in the NFL.
